H i I s'rocx QUorArIon rivnrcnron Application filed April 12,

My invention relates to indicators, and-in particular to devices for indicating the sales prices of securities commonly referred to as stock quotations.

i 5 Frequently, a multiplicity of indicators of of a ticker system to those places in which.

quotation boards are" located. The sale price of the particularitem sold at the ex- 20 change indicated by the ticker 'isrecorded manually on an indicator of thequotation boards. Such boards are, of course, limited to aheight which permits the uppermost indicator to be readily accessible for manual Consequently, if'the current quotationsiof a large numberof stocks are to be displayed, it-isessential that the indicators be compact sothat each indicator occupies a minimum of'space on .the board. It is also essential that the quotation on the indicator be clearlyvisible from any point inthe room.

In accordance with my invention I provide an indicator which is compact andrequires a minimum of space on a trading post or quotation board. The indicator of my invention utilizes polygonal pulleys disposed in aligned pairs, each pair. of pulleys V 7 taken. on the line 4-4 of Fig. 2;

. Fig. 5 is a transverse being independently operable and having a belt composed of linked sections disposed thereover. The linked sections of the belt correspond in length to the polygonal faces of the pulleys and the characters to be disthese sections. V r

' An advantage of my construction is the fact that the characters to be displayedare with the front face of the in- 'mounted on the front shaft and a correplay'ed are formed on the outer surfaces of f 1930. Serial a... 443,697.

comprises aface plate having an elongated opening therein. Extending rearwardly fromtheface plate there are two bracket armson opposite sides of. thetopening in the face plate. The bracket arms support I; two shafts parallel-to the face plate, one immediately back of the face plate and the other spaced rearwardly therefrom. A plurality of polygonal v pulleys are loosely sponding number of like pulleys are loosely mounted'on the rear'shaft. The front and rear pulleys are disposed in aligned pairs :and eachfront pulley has a continuous flangeat one end projecting through the opening in the face plateand available for manipulating the pulley. With each front pulley there is associated positioning and lockingmeans for poslt onlng and locking the pulleywith one face thereof parallel to the plane of theface plate. Disposed over each pair ofpulleysthere is a belt composed oflinked sections, the linked sections corresponding in length to the polygonal faces of the pulleys and having the .charactersto be displayed formed on the outer surface thereof. H t i i l 7 Other advantages of the indicator of my invention will be apparent from the follow- 111g particular description of one embodiment thereof taken in connection with the accompanying drawings in which:

p Fig l'is a front elevation of an indicator,

Fig. 2 is aplan of the same, Fig. 3 is a longitudinal sectional elevation taken on the line 3-3 ofFig. 2;

Fig. 4 is a transverse sectional elevation V sectional elevation taken on the line 5-5 of Fig. 2 and f Figs. 6 and 7 areperspectives of a rear and front pulley respectively. n i

In the embodiment illustrated, the indicator consists of a plate 1 having an elongated opening 2.. therein- The plate maybe secured to a board 3 by machine screws 4. On the rear surface of the faceplate, there is formed a, shoulder 5. The shoulder 5 abutsagainst the board 3 and provides a space between the rear surface of the face plate and the board. A plurality of indicators of this type are generally secured to a quotation board, and the space provided by the shoulders 5 is such that a card on which the particular stock quoted by an indicator is designated, may be inserted between two succeeding indicators. Formed integral with the face plate, there are two rearwardly extending bracket arms 6 on opposite sides of the opening 2 in the face plate. The bracket arms 6 support shafts 7 and 8 parallel to the face plate, the shaft 8 being immediately in back of the face plate and the shaft 7 being spaced rearwardly therefrom. The shaft 8 has projections .9 formed on each end thereof which are received in grooves 10 cut in bosses .11 formed .on the forward end of the bracket arms 6. The shaft is secured in position by machine screws 12 extending through the bracket arm 6 and threaded into the ends of the shaft 8. Intermediate the ends of the shafts, a plurality of transverse .holes 13 are bored in the shaft, the purpose of which will hereinafter appear.

The ends of the shaft 7 are received in bushings 14- which are received in slots cut in the ends of the bracket arms 6. The bushings 14 are provided with parallel flanges between which the bracket arms are received. The outer flanges 15 of :these bushings are loosely mounted on .the bushings and may be forced toward the inner ustingscrews changes the distance between the, center line of the shaft and the bottom of the slot .in the bracket arm. In this way,

the distance between the shafts '7 and 8 may be varied.

A plurality of square pulleys '19 are mounted on the shaft 8 and a corresponding number of like .pulleysQO are loosely mounted on the rear shaft 7. The front and rear pulleys are disposed in aligned pairs. Each pulley is provided 'with a continuous flange 21 at one end and a projection '22 of reduced diameter at the other end which pro ection 1s recelved ina complementary depression in the end of the adjacent pulley. The flanges on the front ,pulleys extend through the opening in .the face plate and are available for manipulating the pulley, the edge of the flange being knurled for this purpose.

Disposed over each pair of pulleys, there is a belt composed of linked sections 23. Each section is bent at each end to form a hinge and is pi-votally secured to adjacent sections. The linked sections of the belt correspond in length to the polygonal faces of the pulleys and have formed on the outer surface thereof the characters to be displayed. The belts are spaced from each other and maintained in position by the flanges .on the pulleys. The front pulleys are so positioned that the link section disposed over the front face of the pulley is substantially flush with the front surface ofthe face plate 1. The width of the link sections is such that together with the flanges on the front pulleys they completely fill the openings in the face plate.

The inner surfaces of the front pulleys have formed at the end of the projections 22 spherical depressions 24:, one for each face of the pulley. These depressions in the inner surface of the pulley .lie, in the sembled structure, .in the plane of the transverse holes 13 bored in the shaft 8. \Vi-thin each opening 13 there is a convolute spring 25 and a metal .ball 26. The convolute spring acts between the base of the bore 13 and the ball '26 to force the ball out of the bore and into the depressions in the inner surface of the pulley disposed thereover. The balls are so positioned that they are aligned with a depression ina pulley when .a face of the pulley is parallel to the plane of the faceplate. The cooperation of the balls and the depressions .in the pulleys serve as positioning and locking means to position and lock the pulleys with one face thereof parallel to the plane of the face plate. A

In the embodiment illustrated, the pulleys are shown as being square in cross-section. The square pulleys are particularly suitable to indicating numerals as they permit the use of a belt containing exactly ten link sections. Of course, in indicating characters other than numerals, it may be desirable to use pulleys having .a greater or lesser number of faces.

It is obvious that .various changes may be made in the embodiment illustrated in the drawings and above particularly described within the principle and scope of my invention as expressed in :the appended claims.
